Slow response to changing workload demands Inability to balance resources between application silos Modern Workloads Present New IT Challenges 14 Poor utilization and/or excessive over- provisioning Server upgrades are expensive and cumbersome Provisioning times are too long and labor intensive Fixed ratio of compute-to-storage results in excessive spending and slow IT response times. No independent scaling of compute or storage

DriveScale Software Composable Infrastructure 16 1) Disaggregate servers into… •  Compute resources (diskless servers) •  Storage resources (JBODs, storage arrays, NVMe SSDs) 2) Compose nodes and clusters by… •  Combining servers with storage via software •  Dynamically re-compose as needs change Two Simple Steps:

Step 1: Disaggregate the Servers Typical Rack Server Configuration DriveScale Pooled Resources Diskless Servers DriveScale Adapter JBODs (Just a Bunch of Disks) Instead of buying servers with internal storage… Start buying diskless servers with external storage

Step 2: Dynamically Compose Servers and Clusters DriveScale Pooled Resources Diskless Servers Easily compose software-defined physical nodes and clusters on-the-fly Combine just the compute and storage resources needed for each workload Easily add, remove or reallocate resources, even between clusters – no more silos! Performance equivalent to bare metal servers with direct attached storage No changes required to the application stack JBODs (Just a Bunch of Disks) DriveScale Adapter

Scalable, Right-sized Clusters From Pools of Resources Cluster 1 Balanced Cluster 2 Storage intensive Cluster 3 Compute intensive Define clusters based on individual workload requirements Diskless Servers JBODs (Just a Bunch of Disks) DriveScale Adapter
